This driver allows usage of CHSC subchannels. A CHSC subchannel
is usually present on LPAR only.
The driver creates a device /dev/chsc, which may be used to
obtain I/O configuration information about the machine and
to issue asynchronous chsc commands (DANGEROUS).
You will usually only want to use this interface on a special
LPAR designated for system management.

To compile this driver as a module, choose M here: the
module will be called chsc_sch.
